Hysterectomy for postpartum hemorrhage in Japan: Diagnostic code validation and nationwide descriptive analysis.

ABSTRACT:

Aim

Hysterectomy is a life-saving procedure for severe postpartum hemorrhage (PPH), but reports on postoperative mortality are limited. This study aimed to describe the rates of hysterectomy and associated mortality in PPH patients using the Diagnosis Procedure Combination (DPC) database, Japan's largest inpatient database.

Method

We first validated the accuracy of PPH diagnostic coding at a tertiary perinatal center, then conducted a nationwide descriptive analysis using DPC data from April 2018 to March 2023. The DPC database includes over half of all acute care hospital admissions in Japan. PPH cases were identified using International Statistical Classification of Diseases and Related Health Problems, 10th Revision codes and blood loss data. We examined hysterectomy rate
